EYEGLASS CONSTRUCTION.

Specification of Letters Patent.

Patented Aug. 83, 1916.

Application led July 2, 1915. Serial No. 37,653.

To all whom 'it may concern:

Be it known that I, CARL E. H. COLLIAN- man, a citizen of the UnitedStates, and residing at Providence, in the county of Providence andState of Rhode Island, have invented a new and Improved EyeglassConstruction, of which the following specification is a full disclosure.

This invention relates to eyeglasses .and an art of making portions ofthe same.

One of the objects thereof is to provide a device of the above nature ofincreased simplicity and durability of construction.

Another object is to provide anfeyeglass construction of inexpensivemanufacture and attractivek appearance.

Another object is to provide in connection with eyeglasses, the lensesof which are slidably connected, means for economizing the use ofmaterial and simplifying .the construction of the connecting parts.

Another object is to provide a practical art whereby devicesvof theabove nature may be readily made.

Other objects will be in part obvious and in part pointed outhereinafter.

The invention accordingly consists in the features of construction,combinations of elements, arrangement yof parts and in the severalstepsand relation and order of such steps, all as will be eXemplied inthe following description and the scope of the application of which willbe indicated in the appended claims.

In the accompanying drawings, in which is shown one or more of variouspossible embodiments of the mechanical features of this invention,Figure l is a rear elevation of a pair of eyeglasses. Fig. 2 is a planof a portion of the same. Fig. 3 is a detailed sectional view takenalongthe line A-Aof F ig. l, showing the parts On an enlarged scale.Fig. 4 is a detailed sectional view taken substantially along the lineB-B of Fig. 2. Fig. 5 is aplanof a piece of tubing. Fig. 6 is a similarVview, showing the part bent to a certain form. Fig. 7 is a similar viewshowing th'e'part'at a later stage. Fig. n is a similar view of thispart mountedin position.

Similar reference characters refer to similar parts throughout theseveral views of the drawings.

Referring now to Fig. l of the drawings, there is shown a pair ofeyeglasses of the type in which the lenses are relatively separable byVsliding connection, but it is to be understood that certain of thebroader features of this invention are susceptible of embodiment ineyeglasses of other forms and that the term eyeglasses is used in abroad sense to denote any device adapted to support lenses upon the faceof the wearer. In these glasses, the lenses l are supported within rims2 of the ordinary channel crosssection having inwardly directed flanges.Mounted upon the glasses are any suitable form of nose-guards 3, theparticular form here shown comprising a pivot wire Il soldered to Atherim downwardly and rearwardly to provide a bearing surface for thesleeve 5 on the nose-guard. The end of the wire is bent, as indicated at6, and retains the nose-guard in position as well as limits its`swinging movement vby engagement with its rear surface, thus allowing afree but limited rocking` movement thereon.

Connected with ,the upper surface of each of the rims 2, as by means ofsolder, is a tube 7 which is cut apart at 8 at a point substantially inalinement with the joint 8a between the ends of the otherwise continuousrims. One of the members 7, as hereinafter described, is provided with aHattened extension v9 of semi-elliptical crosssection as shown in Fig. 3of the drawings. In like manner, the member 7 upon the clpposite rim isprovided with a flattened eX- tension 10 which bears against the lowersurfaceof the extension 9. The part 9 terminates in and is secured to asleeve 1l eX- tending about the pil-rtl() and the latter part hassecuredto its ends a sleeve 12 which holds it in sliding relation to the part9. A coiled spring 13 compressed between the sleeves ll and 12 tendsnormally to urge these apart and draw the members 9 and l() into fullyoverlapped position.

Considering, now, the preferred method of making certain portions oftheabove device, the tube shown in'Figfof the drawings, of suitable length,outer diameter and thickness, is first preferably bent to provide theoffset portion 14. The portion 9, as

shown in Fig. 7, is thereupon collapsed by a suitable die, preferably togive a semielliptical cross-section with a flattened bearing surface.The walls of the tube being of suitable thickness, a resultantcross-section of this flattened portion may be readily soA and,moreover, the hollow construction ofr the tube facilitates this lastoperation. The

offset portion 14, which', being` tubular, is of` a high degree ofstiifness relatively to the metal employed, is then secured, as bysoldering to the desired portion of the rim 2 as shown in Fig. 8 of thedrawings. With the parts so positioned, the tube and continuous rim aresawed apart at the point indicated at 8in Fig. 8 of the drawings. Theinner walls of the tube are then tapped at 15 and a screw 16 passedthrough the severed tube portion and into operative relation with thethreaded part 15.

v In theV use of the device, the lenses are drawn apart in the mannercommon with eyeglasses of this type when they are placed in position,and upon release a spring 13 slides the overlapping portions 9 and 10 tobring the rocking nose-guards 3 firmly against the nose. When it isdesired to insert or change the lenses, the screw 16 is partially orentirely withdrawn, permitting the lens to be snapped within the rim,and the screw is then tightened, securely holding the rim in gives whatis virtually an increased length of connection between the bar and thelens support, for the severed portion 17 of the tube virtually becomes apart of the bridge when the screw 16 is driven home. Moreover, by thisarrangement, the necessity for a separate joint in the rims withseparate connecting devices is avoided, and the employment of a tubularmember, aside from its other advantages, affords a secure and readilyutilized hold for the screw.

'The mounting of the nose pad is also simple and reliable, and variousotherk advantages' in the matter of Vsimplicity and strength of'construction as well as attractiveness of appearance will be obvious.

It will thus be seen that there is provided a device and an art in whichthe objects'of this invention are achieved.

A's various possible embodiments might be made of the above mechanicalinvention and as the above described art might be varied as to theprecise manner in which it is carriedon, it is to be understood that allmatter hereinabove set forth or shown in the accompanying drawings is tobe interpreted as illustrative and not in a limiting sense.

Having thus revealed this invention, I claim as new and desire to securethe fol- Copies of this patent may be obtained for ve cents each, byaddressing the ward the opposite glass,

position. rhis arrangementl lents thereof, by Letters Patent of theUnited Y 1. In eyeglass construction, in combination, a pim, a tubularbridging member' having an uncollapsed portion secured to said rim andacollapsed portion extending towhereby there is attained a bridging-portion of substantially solid and relatively flattened form, saidtubular portion and said rim being cut through at substantiallyregistering points, and means a securing the portions of said tubularmember one to another.

2.
